AP3108LSS9-13

Overview

The AP3108LSS9-13 is an AC/DC converter from Diodes Incorporated, packaged in SSOP-9. It functions as a single-ended continuous conduction mode (CCM) controller designed for offline flyback applications. The component supports input voltages ranging from 90VAC to 264VAC and delivers up to 45W of total output power. It integrates DCM/CCM PWM switching capabilities with synchronous rectification control logic to achieve high efficiency standards.

Feature Summary

• Integrates primary-side PWM switching and secondary-side synchronous rectification control
• Supports USB Power Delivery 3.0 protocol compatibility
• Optimized for low standby power consumption under no-load conditions

Applications

• USB PD 3.0 wall adapters
• USB PD 3.0 automotive chargers
• High-efficiency offline flyback power supplies

Procurement Notes

Verify the specific suffix 'SS9-13' against official Diodes Incorporated documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to confirm current manufacturing status and compliance certifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring integrated primary and secondary control to reduce bill-of-materials count. It is suitable for applications demanding DOE Level VI and CoC Tier II efficiency compliance. Consider the SSOP-9 package constraints and thermal requirements when designing the heat dissipation strategy for the printed circuit board assembly.
